Yes, buy your N7 and get it working just the way u need it to be way before it goes in the dash. Plan for a way to get to it physically in case it shuts down behind the dash for whatever reason. Or extend the buttons like some other ppl on the internet have done. Install Clockwork recovery mod or whatever custom recovery u want along with Timurs FI Kernel and ROM. Also install a launcher so u can back up the tablet and also use Titanium backup....I consider it a must. As for the electrical connections, I kept it simple....N7 to a usb Y- Cable going to a switch that I wired into a ignition on power on wire which then goes to a cigarette plug connector from walmart with 2 connections, usb 1.0 and 2.1 amp charge. This eliminated the guesswork for me. The hub as well, plugged into a usb 1.0 amp cigarette barrel connector and walmart charger that plugs into it. The cigarette connector is available at walmart, target, etc. Everything else is pretty well detailed in this thread and others on-line. I will be posting pics of my build here soon....its pretty much the same as Kuchar's....he really did a good job and filled in my gaps.....
[Nexus 7 General] eastside770:
Hey Kuchar09 do think it would be a way to wire the power button to the ignition switch? for instance turn the turn on ign switch the screen turns on and vice versa for powering it off?
[Nexus 7 General] Kuchar09:
Umm that wouldn't work. Why not setup a task in the tasker app so once the tablet is charging the tablet screen turns on?
[Nexus 7 General] eastside770:
i have it set up like that..Im just trying to find ways to keep my music there and ready to play without have 2 reload it every time I crank my car up. I have ALOT of music.
[Nexus 7 General] daclothe:
2 tips that have been helpful to me is to set a fastboot command so that the n7 boots when it receives a charge and also to always have a small magnet to wake the screen if need be. those two have saved me countless times from pulling my hair out.
[Nexus 7 General] eastside770:
How does the small magnet work?
[Nexus 7 General] timmgrimm:
It signals the screen to turn off and on. All the cases with automatic screen off and on when you close/open them, have a small magnet in them. My guess is that its part of the tablet design.
[Nexus 7 General] daclothe:

it's basically this sans all of the cover nonsense.

i can slide my magnet by the sweet spot and voila it comes on.

Hey Kuchar09, thanks for all your info here; you truly are a legend of the in-car dash. I've been watching the happenings for a while, so although this is my first post, I've read through everything.

I'm relatively new to the world of in-car modifications, so I just wanted to get some clarification around your wiring setup:

- What are the black bulb-like enclosures you've installed the USB charge ports in?

- Following on from that, how have you wired the USB charge ports? Normally you plug them into a cigarette lighter, you seem to have wired / soldered them to another cable?

- I notice with your cooling fan it is also wired in; where abouts did you wire it to? I assume you needed molex cables / a cap connection piece?

- This is a big ask; would it be possible for you to draw / create some photos of how to make your specialised USB cable? Even some suggestions would be helpful. These are a very clever creation and circumvent a number of issues that people have been running into on other forums.

Finally, would anyone have some recommended sites or pages to read through for a noob in car wiring? I'm particularly interested in learning about wiring in to the ignition wire (want to make sure I do this properly) as it makes me just a touch nervous.

Thanks again for all your awesomeness, I really look forward to installing this project.

Rotate through Apps

For the OP.

I understand how the steering wheel buttons are wired up.

I am wondering if you used Tasker to handle/intercept the SOURCE button on your steering wheel?

I see you can flip through a few running apps by pressing your SOURCE button.

How did you accomplish this?

Thanks

I saw your video and spent the better part of today extensively testing with my BT headset with both talkatone and grooveip.

Here's the short of what I got working (I used Soundabout vice BT Mono)

- N7 voice commands from BT mic, audio out 3.5mm jack for my car audio

- BT from talkatone and grooveip - BT mic works great (tested to skype) but rcv audio in the headset is pure static, I can hear myself in the background from my PC mic

What I'd like to be able to do with this setup is..

- N7 BT mic for voice commands in android, audio out speakers (3.5mm jack)

- N7 BT mic for use in talkatone/grooveip (some reason they force the rcv audio to the BT headset once its connected to the call)

Were you ever able to get it to work that way with either of those apps?

Here's some pics of my install, I haven't added USB support yet, just looking into that now.

I'm running strictly off the 3.5mm stereo output though my car's sound system which maintained my stock headunit's complete functionality (XM Radio, FM/AM, etc).

My USB cable from the N7 is run to my center console storage area so I can still connect my laptop over USB if needed.

Do you think this usb dvb is good for timur kernel ? http://www.ebay.co.uk/itm/Newsky-TV...ther_Computing_Networking&hash=item2323607b5b
[Nexus 7 General] Kuchar09:
- What are the black bulb-like enclosures you've installed the USB charge ports in?

DC plugs Which I have one wired constant power for my DAC and one tied into ignition for my other hub.

- Following on from that, how have you wired the USB charge ports? Normally you plug them into a cigarette lighter, you seem to have wired / soldered them to another cable?

I just wired 3 DC outlets to my car wiring to use the adapters listed above.

- I notice with your cooling fan it is also wired in; where abouts did you wire it to? I assume you needed molex cables / a cap connection piece?

Also connected to the ignition wire. It came with a 4 pin to 3 pin(maybe 2) connector which I cut and connected that to the ignition wire so I can unplug the fan. other wise you can just cut the wires to the fan and use any type connectors.

-This is a big ask; would it be possible for you to draw / create some photos of how to make your specialised USB cable? Even some suggestions would be helpful. These are a very clever creation and circumvent a number of issues that people have been running into on other forums.

I kind of did this in my wire diagram but I can make one of just the 2 connectors you need soon.

-Finally, would anyone have some recommended sites or pages to read through for a noob in car wiring? I'm particularly interested in learning about wiring in to the ignition wire (want to make sure I do this properly) as it makes me just a touch nervous.

I'd recommend looking at a fourm that is specifically for your vehicle and find a wiring diagram for a constant 12V(depending how you plan to wire yours) and a ignition 12V source.

talkatone/grooveip work no problem with a bluetooth headset without any extra software. It is every other app that you want to use a mic input that you get static which is when you need BT Mono to enable your headset.

Make sure the little icon shows up in the status bar so you know it is actually active.

With my current setup I never tested talkatone/grooveip but I would think they would work. I'll get a new video up with my sun visor speakerphone in action soon.

Very nice install by the way!!!

I'm not positive but I believe that should work! That was defiantly on the compatible list for SDR Touch when I was looking at DVB-T tuners.
[Nexus 7 General] Beakfire:
Thanks and that's strange, I think maybe misunderstood.

Here's a little more - I'm trying to use the BT headset off of the Nexus 7, not my phone, which is where I'm getting the static from. I could use it off of my phone without problems and use tablettalk to answer/dial calls.

I'm on stock 4.2.2 though, just rooted and unlocked. Just ordered a USB Hub and P/S to add the USB support, so probably going to flash USB-ROM soon. Something may be a bit different with the setup under USB-ROM I guess.

Also I'm using Soundabout Pro, it doesn't have the static problem like the BT Mono app when it's enabled and you use it with google voice or something.

Here is a little preview of Turbo UI which will soon be included in USBROM!! Turbo UI is based on HTML5 and is completely customizable to your liking with a little programming. So keep in mind that this is not how your launcher has to look like.

Keep your eyes open for this in the future, It is going to be a big hit!!!

Oh and if your wondering how this compares to my old UI... Well this is 10 times better!!!

[Nexus 7 General] Kookie_Monster:
Hey Kuchar. Already had the chance to congratulate you on the fine job you're doing.

The fine tuning is driving me crazy. lol But you're absolutely right... it's gonna be awesome and the potential is huge.

Here's a new layout I was working on last night:

I just picked up my Sabre USB DAC and I have some other things I have to test on my N7, and probably won't have much time to work on it for the next few days. I'm pretty excited about it though. :fingers-crossed:
[Nexus 7 General] count-jarvis:
Thanks Kuchar09, very helpful! Look forward to seeing the modded USB cable.
[Nexus 7 General] Kuchar09:
You need to buy 2 of these and cut one in half and tap into the un-cut one like the image below.
[Nexus 7 General] timmgrimm:
OP: so what ROM/kernals are you running?

I'm currently running the Modaco rom with no complaints. The main reason I ask this is because I see that Timurs room paired with CM 10.1 offers much more functionality.

I've enjoyed the fact that Modaco is practicality stock+.

Well I see myself changing over, just curious your/ and others setup. Thanks.

I was going to edit this because I realize now that you are using Timur's rom /CM 10.1. But I'm still hoping for feedback so......
[Nexus 7 General] Kuchar09:
I'm running Timurs most recent version of USBROM rom which is based off CM 10.1.
[Nexus 7 General] naiku:
Kuchar, do you have your Joycon mapped to open any applications on your Nexus? If so did you just enter the path to the program in the Joycon software on your laptop? Mine arrived today, and while I have the basics figured out, I want to be able to have one of the buttons on my steering wheel open a specific app.
[Nexus 7 General] Kuchar09:
Sure do!!! Its possible using an app called external keyboard helper and making custom keyboard shortcuts. Here is a video of how to do it.

[Nexus 7 General] jeb192004:
I'm having some issues with the nexus 7 I purchased last week. Wondering if I can get some help. Its installed in my 12 impala with the charger wired into the ignition switch. Earlier this week leaving for work I was putting it back in my dash and plugged the charger in and my car lights flashed and I got a message in dash saying "service security system" and I couldn't start my car until I unplugged the charger from the tablet. After that my nexus 7 wouldn't recognize the charger being plugged in until I rebooted it. Last 2 days I've had no issues. Then this morning I was leaving for work(tablet already in dash) I tried starting my car and a message appeared in my dash "battery saver active". I unplugged my tablet again and I was now able to start my car again. Wondering if anyone else is having trouble with their nexus 7 and the charger...? Should I take it back to the store where I bought it and get a new one or is there something else goin on here? I never had any issues with my og galaxy tab that was previously installed... I know its not the charger cable cuz it works perfectly fine with my phone...
[Nexus 7 General] hiragasait0:
Well, that's nice. How do you use it on real daylife ?
[Nexus 7 General] Kuchar09:
Humm idk. I was going to say check your wiring but since you said you had a galaxy tab in there previously I don't think that is the issue. Maybe try a different charger by chance. Sorry I can't be more help. If you figure it out post it on here in case others have the same issue.

You mean the whole tablet install? I love it!!! It is so much better than my factory stereo system and I don't have too many major issues that a restart won't fix..

problems with usb camera

I want to install nexus seven in my car. My requirements are not as complicated as your as . I am a novice and dont want to take a big leap as my first step. I want to connect nexus 7 to logitech c270 web cam

After following your thread, I have tested simple webcam app with logotech c270, It worked well when connected directly but didnt when connected via usb . So I have decided o install usb rom, did that but couldnt acomplish what , I wanted.

My battery is charging directly from ac charger, via usb hub from ac charger. Tablet can recognise pen drives but cant recognise usb web cam ( it is working, tested with my laptop) . I have installed GAPPS and my previous market apps got installed automaticaly. In that process stick mount was also installed. I am able to mount external pen drive but not the camera. I have removed the pen drive without unmounting , got a message that pen drive is removed unexpectedly. Later on my tablet is not recognising any external drive even connected straight to it via OTG cable without hub. But it is charging even via hub. I have restarted the tab several times, charged once after complete discharge.

I am unable to get to developer option by tapping about tablet 7 times (regadless of how quick I tap) as about tablet scree is opening after few taps , probably after 3taps, as I am seeing a message that i am 4 taps from developer option.

I am attaching a file showing my intended setup.

Thank you for your help.
[Nexus 7 General] jeb192004:
Did some searching on Google yesterday and found that quite a few other people are having issues with the usb port on the nexus 7 as well. I decided to take mine to gamestop and exchanged for another one. Hopefully I won't have any issues with this one.

Got my joycon in the mail yesterday. Can't wait to try it out. Not sure when I'll get to mess with it tho. Its been raining here the past 4 days and not supposed to quit for another couple days...
[Nexus 7 General] naiku:
Hey Kuchar, I need your help with some Joycon expertise. I have spent a good bit of time searching, but there is surprisingly little info out there. In my car I have 4 buttons. 2 are scroll wheels with an up/down and a click function, the other 2 are simple buttons. The biggest issue I am having, is that Joycon Explorer is reading the click on one of the scroll wheels, as the same resistance as the simple buttons. What that means is I am unable to program everything. If I click the scroll wheel button in first, when I then push the separate button, it reads it as me pushing the scroll wheel click again.

The other issue I have is that sometimes when I scroll up / down on either of the scroll wheels, it does not always recognize it. Sometimes I have to scroll twice (the scroll wheel has a kind of click feel to it) before it is recognized.

Any idea's what I can do to figure out both of these issues? While I am happy enough if I can get track forward/back, pause, volume up/down and mute. I would like to be able to program the additional 2 buttons to do something (see my earlier question about programming a button to an app).

Thanks.
[Nexus 7 General] jeb192004:
Well...the problem is not the nexus 7. Was programming my joycon and tested it out and it worked great. But...having the nexus(not rooted and no usbrom like before) plugged into my otg y cable and plugged into the charger, which is wired into my ignition wire goin to my cars computer caused my car to screw up on me again. I'm thinking that using the otg cable might be sending a signal back to my cars computer. So I think I need to find a wire that's only powered when the car is on that does not go to the computer. I have no issues at all if I just plug the charger into the cigarette lighter.
[Nexus 7 General] Antonnio:
well finally my galaxy tab 7 is working on my car without problems, to avoid any kind of ground issue i use a logitech bluetooth adapter with RCA outputs, the adapter is powered by the 12V ACC cable of the car, we make a little regulator to change the voltage from 12V to 5V....

to charge the tablet i use the cars cigarette outlet with a dual USB charger.

so everytime that i start up the car... the bluetooth adapter power up and the tablet wake up.

this is my setup

galaxy tap ---> bluetooth adapter ----> DB Drive EQ 8Volts ----> 2 x amps (for speakers and woofer)

install Profile Scheduler to manage the power in the tablet, create a profile to turn and keep on the screen, set brightnes to 70%, enable bluetooth, gps and wifi, launch my music player n7

also create a second profile. that after 15 seconds turn off the screen, close the music player and disable the gps and bluetooth, when the tab is not charging

use the player n7 for my music

isntall waze and torque.

i will try to upload some pictures of my tab installation.
[Nexus 7 General] shigga:
I've installed my n7 in the car. Using USB ROM. Is anyone having an issue listening to music while using Google navigation. My music all force closes. I'm running the latest beta and also tried the stable version.
[Nexus 7 General] Kuchar09:
Humm not sure how to fix the second issue. Only thing I can think of to make your buttons have different resistances would be to take the buttons apart and add a resistor inline or something, since there is nothing that I know of that we can do to the joycon to fix this.

Maybe try to tap your power source into somewhere else like the power wire going into your cigarette lighter. Unfortunately this is kind of a weird issue and think the only way you will be able to solve it is with trial and error.

simplewebcam not displaying the camera output

Hi, Kuchar,

I need your help.

I am trying to install nexus 7 in my car. At present, I am testing the set up. I have installed USBrom latest stable. connected the tab to ac charger via otg y cable. i am able to power the tab. Tab can recognise a flash drive attached to the cable directly. It seems it is also recognising logitech c270 web cam (compatable camera, I have tested it on same tab with stock android and simpleweb cam apk) as I can see changes in the system log when camera is connected and disconnected. When, I start the simple webcam app , I am unable to see the camera output.

I have stickmount installed, Shall i unistall it?

Another thing I have noticed is when I connect flash drive I getinng a message from stick mount , "open stick mount when the usb device is connected" . Even when I remove flash drive after unmounting it from stickmount, I an getting a message that the usb storage is unexpectedly removed. Stickmount is not starting when usb web cam is attached.

I dont know how to use pastebin to send the log info.

Shall I uninstall stick mount and supersu as these facilities are inbuit in the rom. These were install on stock android and were restored back when I restored the apps.

Many thank for your help.
[Nexus 7 General] naiku:
I think I know how to get around this, just program the extra buttons onto another of the Joycons inputs. So, I have my 2 scroll wheel buttons on input A, and the additional 2 buttons on input B. At least I think that would work.
[Nexus 7 General] Kuchar09:
The only problem with that is that input 1 will still be be getting the scroll button even though you have the scroll programmed on input 2 as your other button that has the same resistance so basically both inputs will be launching at the same time.

Unless your taping your input 2 into a different wire than your input 1. But if both wires are taped into the same wire then I believe you will have the above problem.

Let me know how it works out tho!
[Nexus 7 General] naiku:
I thought the same as well last night, I may give it a shot though to see what happens. Or at least to see if the resistance values are slightly different, when I press the button it shows up as a value all the way to the left. Will be nice if it works, but if not, I at least have the basics working.
[Nexus 7 General] Kuchar09:
I feel like they have to have different resistances in order for the stock radio to tell the difference between the buttons.

Of course maybe your car is setup different then mine and I am completely wrong lol
[Nexus 7 General] eastside770:
@Kuchar09 have you thought about hacking the onstar gps to the n7? And does The obd scanner send gps info to the n7? If yes does that assist the gps trackin on the n7?
[Nexus 7 General] timmgrimm:
OP: what method did you use to solder your power/volume buttons?
[Nexus 7 General] ch3mistry2222:
how much is it?
[Nexus 7 General] Kuchar09:
Umm haven't really looking into using my onstars gps since I haven't had any issue with mine yet. The obd scanner only scans the pids of your car and has no gps inside, it actually uses the gps inside the nexus.

I used the method found in this link. I did it still on the nexus you just need to be extra careful. Oh and don't forget the hot glue.

Total = $610 this is with me going all out tho.

I plan on doing an install for a friend and keeping the total price under $300. This also includes an amp and speakers!
[Nexus 7 General] slaxer07:
That is exactly how they work. Module's usually looking for a a specific resistance within a certain range so it can differentiate between the different buttons.

Do you get good reception with your tuner? The one you link to isn't available now, so I purchased a different and reception is horrible.
[Nexus 7 General] Kuchar09:
Ehh its decent but nowhere near my stock radio. I haven't really used SDR touch too much to really tell you since its kinda pointless without the memory stations right now, well pointless to use while driving anyways.
[Nexus 7 General] Mperkins92:
Id like to start out that your thread inspired me to install my N7 in my s10.

After a lot of suspensful cutting of the dash to fit the N7 display i've finally got my tablet roughed in and I'm currently running audio from a 3.5 mm jack to the amp and just a charge cable straight to the tablet (this will change when i have money again). Everything has been working beautifully except most of the time when i try to use the voice recognition it doesnt work and also i've got the default navigation and if im playing music and the navigation wants to tell me about a turn instead of just talking over the music both applications will shut down. The problem is gone when i turn the voice off but i'd like to get my turn by turn speaking back. I'm curious if this is because of the way i have the audio hooked up. or another problem. Thankyou!
[Nexus 7 General] Izzmeister1978:
Hello guys, I have been running the N7 in my dash for a few months now. I have had some issues but nothing major, it does seem to have a RAM leak. Darn think freezes due to no RAM available every 2-3 days....it's annoying. I have tried looking at the logs, running watchdog app etc.....whatever.....has anyone tried installing the new Samsung Note 8.0 in the dash yet? I'm gonna get it today and start looking into replacing my N7 with it....just the next best android tablet out now.....it's also got a microsd card slot and a better screen in person....been reading the forum for info on rooting, etc....looks like it's a go. What I am wondering is if I need a diff rom and kernal to make the sound come thru the usb DAC? Guess I will find out....if not and this is for Kuchar....would Timur likely write a kernel/rom combo for FI wit this tablet....I was playing with it at BEst Buy....it's PREEEEETY.....lol :D
